Wow thanks for all the cool info!
Now that has got me thinking wonder if they make TV dinner style trays out of pyrex glass with a plastic cover. I would rather use something reusable instead of generating all that waste. I like the idea of the trays though, perfect for bringing a meal at work. That's one thing I really need to start doing more. I'm just not equipped for it (knowledge and equipment wise) so I need to get on that.
For spaghetti sauce and juicing I actually use mason jars, what's nice is they are dishwasher and microwave safe. You CAN freeze juice in them too as long as you leave some space for expansion, it will expand up and not sideways so they wont break.
Also bought this TV dinner the other day, it's suposedly healthy, it was steamed vegetables in a sauce, was actually really good. I don't imagine it would be that hard to make that myself... I need to buy a steamer.
Ideally I would only use reusable containers, but there are 3 factors for me:
1. Cost
2. Space
3. Tossability
The first is that a 150-pack of containers is like $60, which makes them under half a buck each. Glass & permanent plastic stuff are easily ten times the cost, so if you want to do bulk make-ahead meals and stock a deep freezer with 40 or 50 containers, that's several hundred dollars worth of containers.
Which is fine because eventually the cost of the disposables will caught up with the permanents, but you also have to factor in the space issue: glass & thick plastic tends to take up more space than thin, Chinese takeout-style trays. I can fit a whole lot more containers in my freezer with the throwaway ones than I can with my Tupperware or Pyrex stuff, plus I have more room in my lunchbox this way.
The third is tossability. I like having the option to throw them away, especially since both my job & my school having recycling trash cans. I'll sometimes bring my lunch in a plastic grocery bag, with plastic utensils, in a plastic container, so the whole thing can get recycled when I'm done (and I don't have to do the dishes, yippie!). So there's a big convenience factor if you're usually in places where you can't easily rinse out your dishes, or don't want to do them when you get home.
There are a lot of neat technologies out there. There's the stoneware TV dinner trays linked earlier. Glad now has freezer-to-oven reusable containers as well:

And of course the ones off the Web Restaurant store:

My main office recently got a toaster oven (yay) so that's a viable option for me now. Barring that, Rubbermaid also has some nice reusable containers that do pretty much everything except the oven:

I have an electric steamer & it's pretty great. It depends on what you want to do, however. For example, I buy huge bags of frozen veggies from Sam's Club, and I've found the easiest way to heat up small serving sizes is to get a microwave-safe bowl, pour say frozen broccoli in it, and put water on top so it's more or less covered (I use cereal bowls), then microwave it for 3 to 3.5 minutes. The steamer can sometimes make it too mushy, and sometimes I only want to do a smaller amount for a single tray or two or three trays. So while it's still a good option, especially for steaming in bulk or for your family for dinner, the microwave trick is actually what I use the most!
As far as mason jars go, I'm a big fan. I use wide-mouth ones, usually with the plastic-screw on lids & some labels. Here's a pic I posted over in the

I also have the Foodsaver vacuum-seal attachment for storing stuff airtight. Later this year, I'd like to pick up a pressure canner, particularly for canning meats. All in good time though
